Michael McCandless 856b294441 Core: let Lucene kick off merges ... Today, Elasticsearch has a separate merge thread pool checking once per second (by default) if any merges are necessary, but this is no longer necessary since we can and do now tell Lucene's ConcurrentMergeScheduler never to "hard pause" threads when merges fall behind, since we do our own index throttling. This change goes back to letting Lucene launch merges as needed, and removes these two expert settings: index.merge.force_async_merge index.merge.async_interval Now merges kick off immediately instead of waiting up to 1 second before running. Closes #8643		2014-11-25 04:13:57 -05:00
